Front hub conversions in particular are very easy to do and produce reliable, efficient and nice to ride bikes. Bafang even has a plug-n-play set of controllers and torque sensing bottom brackets that can do proper torque assist. I’m using one of their BBs with my current non-Bafang setup and it’s spectacular. It makes riding my bike pure joy. 😁

I’m currently using a light read hub, but if I was building a new bike, I’d go with a light front hub on a steel fork. The total weight would be down even after adding the extra weight of the fork and the rear drivetrain can stay stock.
